Things to Remember
- Forsythia are grown from cuttings. Select cuttings from new growth. Cut a three to six inch branch, and place the end into moist soil. Keep the soil moist to aid rooting. Rooting should only take a few weeks.
- Water plants during extended dry periods as needed.
- Fertilize plants once a year in early spring. Use a high phosphorous fertilizer to promote bright blooms.
- Flowers form on prior year’s growth, not new growth. So, it’s important to prune them immediately after the flowers have bloomed.
- You can cut back old growth to about four inches from the ground.
- Forcing Forsythia to bloom indoors is a snap. Simply cut off a few branches, and bring them indoors. Put them in a vase with water. A couple weeks later, the branches will burst into bright cheerful, golden yellow blooms, right in the dead of winter
